Yep, thanks Justin, both your points really made the difference, because I do believe that the buffered socket write is the key component for the 3-time improvement that I'm getting (from using FastHTTP), IMHO. And FastHTTP recommends GOMAXPROCS=1 too, which I used this time as well.
So thanks again, Justin & Ronny!
